Hi all, I did not dig too much before posting.
Is anyone here in a committed relationship but not legally married in the country, and with no plans to do so, or close to anyone in this kind of relationship? (not sure if there is a term for that)

What would be the downsides for couples who are not legally married in this country?
What are the obvious legal complications? Can't legally have kids? (Exclude inheritance rights, social, religion and cultural perceptions please)

Thanks!
